Sorry for my crazy writing initially, I was very frustrated.  Anyway, line 5d is saying it is "From office in the home" under Real Estate Taxes (Line 5).  But the real estate taxes was auto in ported from 1098 on line 5b. 

It is not the total, the total is on 5b in the column to the right of the subsections of 5. I just can't out under 5 Real Estate Taxes how 5d is being calculated.
